Chernobyl had a higher death toll than FukushimaWhile evaluating the human cost of a nuclear disaster is a difficult task, the scientific consensus is that Chernobyl outranks its counterparts as the most damaging nuclear accident the world has ever seen.
How many of the Fukushima 50 have died?
Degraded living conditions and separation from support networks are likely contributing factors. As of 27 February 2017, the Fukushima prefecture government counted 2,129 "disaster-related deaths" in the prefecture.Is Fukushima still leaking radiation?
These areas still have relatively high radioactivity. The half-life of radiocesium is about 29 years, meaning the quantity of the radioactive material should drop by half by roughly 2041. The leftover radiation from the much larger Chernobyl disaster of 1986 roughly follows that pattern, Johnson says.How long did the Fukushima earthquake last?
